Lighting fixture



FIG. 1 is a bottom plan view of a lighting fixture showing my new design;

FIG. 2 is a bottom perspective view thereof;

FIG. 3 is a side elevational view thereof as seen from the direction of lines 3-3 in FIG. 1, the similarly rotated sides being identical thereto; and,

FIG. 4 is a side elevational view thereof as seen from the direction of lines 4-4 in FIG. 1, the similarly rotated sides being identical thereto.

The top of the lighting fixture is not part of the claimed design and therefore is not shown. 

The ornamental design for a lighting fixture, as shown and described.
